I've heard this was necessary when installing the Fall-Line/VAC one as well...ill check to see if this one requires a similar installation method. I mean eliminating the factory center support bearing removes some of the 'flexing' capability during installation...so this really wouldn't surprise me, but I'll ask anyway.

One member stated that it was impossible to separate the driveshaft from the rear differential and CF driveshaft joint had to be removed and cut off.

There are more threads like this, I just don't have the time to search right now.

The Fall Line/ VAC is not supposed to have this problem.

The original (ACT? something like that) had no flanges to remove it from the diff and no expansion/compression area.

The Fall line/VAC had vibration/failure issues at speed.

... hopefully third time lucky on CF drive shafts! I'd love to get a good one that wasn't hugely compromised in one way or another!

I was really hoping you would chime in. I read a lot threads where you were in involved in the discussions.

I agree with you, honestly it is only matter of time before we finally get one that works.

Yes, it's sad no one can make a proper aftermarket one!

Vibrations over 100mph are a big no no, especially as some here frequently go to Mexico to let the cars run!

Hopefully this will be the ticket Stash

Yeah, I believe that was sold by ACT (as Ian stated), and it proved itself as not a realistic option just based on the installation/removal drama. I'm not here to poo-poo any previous attempts from other vendors to bring a cf driveshaft to market...I'm just unwilling to compromise or settle for what's currently available as I believe they all have certain drawbacks. I'm looking for something as plug-n-play as possible w/little to no vibration at speed, and no long term adverse effects on the car's drivetrain. We'll see...

Yeah, let's hope so...would be a win for the community! I'll remain cautiously optimistic!

100% agreed and if they release a CF driveshaft that fills those same requirements I will be buying it.
